Superconductive flat plate solar water heater

Abstract

The invention discloses a superconductive flat plate solar water heater and belongs to the field of flat plate solar water heaters. The superconductive flat plate solar water heater comprises a water tank, a superconductive pipe, a condenser and a heat collector, wherein the condenser is provided with a capillary. A heat collecting pipe of the heat collector is composed of a thick copper pipe in the vertical direction and a plurality of thin copper pipes, one end of each thin copper pipe is sealed, the other end of each thin copper pipe is communicated with a pipe wall of the thick copper pipe, each thin copper pipe forms an included angle of 1-5 degrees with the horizontal direction, and the sealed ends of the thin copper pipes are located below the horizontal line. The bottom end of the thick copper pipe is sealed, the top end of the thick copper pipe is provided with an opening, one end of the superconductive pipe is inserted in the thick copper pipe in a matched mode through an opening, the other end of the superconductive pipe is communicated with the condenser, the condenser is installed in the water tank, and superconductive liquid is injected into the superconductive pipe. The superconductive flat plate solar water heater is in split type design and is simple in structure and convenient to install, the maintenance rate is zero; and the superconductive flat plate solar water heater runs at a stagnation temperature, is high in heat-collecting efficiency, absorbs heat quickly and is longer in service life.

Description

technical field [0001] The invention discloses a superconducting flat solar water heater, which belongs to the field of flat solar water heaters. Background technique [0002] Generally, a flat-panel solar water heater is composed of three parts: a heat collector, a water tank and a pipeline system. The hotter medium exchanges heat with the colder water in the water tank, so that the temperature of the colder water in the water tank rises, and the hotter medium cools down and then circulates to the water inlet of the collector. Such a continuous cycle of heat exchange achieves the purpose of heating the water in the water tank. According to this method, when the heat collector is in use, more pipes and valves need to be installed, and the heat transfer medium must be filled, which is inconvenient to install and requires manual maintenance during use. Since the heat transfer medium used is generally ethylene glycol aqueous solution or water, the heat that the ethyle...

Problems solved by technology

According to this method, when the collector is in use, more pipes and valves need to be installed, and the heat transfer medium must be filled, which is inconvenient to install and requires manual maintenance during use.

Since the heat transfer medium used is generally ethylene glycol aqueous solution or water, the heat that the ethylene glycol aqueous solution or water can take away after being heated through the flow channel of the collector is not much, so the heat collection efficiency is not high enough
